1. The problem statement, all variables and given/known data

A 52.9 g ball moves at 12.2 m/s.
If its speed is measured to an accuracy of
0.04%, what is the minimum uncertainty in
its position? Answer in units of m.



2. Relevant equations

delta x times delta p = 1/2 (h/2pi)


3. The attempt at a solution

I used the uncertainty of the speed to determine the minimum and maximum momentums for the ball. I used these to determine what delta p is equal to (0.6195648) and then substituted that number into the equation to solve for delta x. I used kilograms for the mass, which I believe are the correct units as opposed to just grams. If you could help me determine what I am doing wrong, that would be great! Thanks!
